It's not mine :-) It's the 'obvious' mathematical definition of 'normalised'. > > I am also wondering if the conversions to B-format > > /FMH be more clear if given as full equations, eg: > > > > X = X1 > > R = X20 * sqrt(5/4) > > yes, I've done that Hmmm. The column heading says 'conversion to B-format/FMH', and the values are prefixed by an 'x'. This suggests that to get FMH you have to multiply the N3D component by the value listed. But it's actually the inverse: as multipliers, these values convert *from* FMH to N3D. And they all include a spurious gain factor of 1/sqrt(3). Ciao, -- FA There are three of them, and Alleline. _______________________________________________ Sursound mailing list [email protected] https://mail.music.vt.edu/mailman/listinfo/sursound
